SOURCE: 2001 VW Passat AUG Oil Pump replacement - how to get around support beam

Best thing to do is to undo the engine mounts and lift the engine up. You can use an ond seat belt and a strong peice of wood that will fit accross the engine bay. You can use a tie-down ratchet as well to lift up the engine as it will make things easier. then you'll have more room to remove the pan. Cheers.

This is probably a head gasket problem and not an oil cooler problem.

The oil cooler is fairly easy to test.

Remove the cooler from the engine but do not disconnect cooling lines and then pressurize the cooling system. You can use a radiator test tool to put pressure on the cooling system and look for leaks. If it leaks, replace it.

You may also be able to bypass the oil cooler altogether if it leaks.

The head gasket is another story.

Get a 1/4" pipe to spark plug fitting and put a male air coupling fitting in it.

Then you can charge the cylinders with air from your compressor.

Make sure each cylinder that you test is at top dead center so that the valves are closed.

If air bubbles into your coolant, you found your problem.

If air leaks out your intake you have a bad intake valve

If air leaks out your exhaust you have a bad exhaust valve etc.

Could be just the OIL COOLER. VW IS CORRECT.
If the oil cooloer fails internely you will have a mix of coolant and oil. In the engine and in the Radiator,

But not to say the other guys were wrong...

replace your fuel filter first. If that does not do it, then try an air-flow meter. (if the check engine light is on it may be an airflow meter.

I have oil in the coolant of my 1999 VW Passat 1800 sport, engine code APT. Although on the face of things it looks to be a head gasket failure, I have been told that it may well be an oil cooler issue....


The oil cooler is almost definatly the problem

The reason for this is.

Your oil pressure is normaly anywhere between 2 and 5 Bar depending on engine temp and oil type, where your water pressure is never more than 1.2 bar. Thus the oil pushes into the cooling system due to the fact that it is of higher pressure.

In the event of a head gasket leaking it will push water into the oil not the other way round causing the oil to eventually go white.

These cars are known to have problems with their oil coolers from time to time.

Have your cam seals checked. Cam seals are a big problem on these cars and a major source of oil leaks. Another source is the oil cooler gasket but that doesn't appear to be the issue here as your leaks are well above the oil cooler. Good Luck.

Oil light and brake lights blinks on and off and abs light is on


Just a idea. If the car is running at idle and the oil light blinks , it usually from low oil pressure. At a idle your seeing the light respond to the revolutions of the engine. ! thing to try is to replace the oil pressure switch on the engine block. And #2, Most causes in a VW is that the vehicle overheated at one time and weekend the oil pump,or massive amount of miles.
